A key to a great defense is having a great pass rush. To do this, you need great defensive ends.

That's why defensive ends will be in high demand in the 2013 NFL Draft. Teams will do what they can to secure the best of the bunch.

Which players will join Damontre Moore as the best defensive ends in this class? Read below for more.

Damontre Moore, Texas A&M

Von Miller was the last great defensive end from Texas A&M and Damontre Moore is ready to follow in his footsteps.

Moore, a 6'4", 250-pound speed demon, had a terrific season this year. He had 12.5 sacks and was consistently in the opposing backfield.

Moore had big games against quality competition, including three sacks against Florida.

He's the next great defensive end and should be a top-five pick. Many teams will be interested in his services and whoever gets him will be better off for it.

Sam Montgomery, LSU

Montgomery had a fine season for the LSU Tigers. He had seven sacks, 32 tackles and 12 tackles for loss.

Montgomery has great size at 6'5", 260 pounds and is faster than Moore. He had big games against Alabama and South Carolina.

One area of concern is that Montgomery was completely shut down by blue chip left tackle Luke Joeckel of Texas A&M. Joeckel projects as an elite left tackle in the NFL. If Montgomery struggles against him, he may struggle against other elite NFL left tackles.

But Montgomery has speed, strength and explosiveness and possesses the overall skill set to be a starter in the NFL.

Look for Montgomery to be selected in the first half of the first round.

Bjoern Werner, Florida State

Werner is another big defensive end who had a big season. Werner had 13 sacks, 40 tackles, 18 tackles for loss, seven passes batted down and a forced fumble.

The 6'4", 255-pound Werner is a strong physical specimen. He uses his strength to bully offensive linemen and push them into the backfield. The German also excels as a run defender, and is probably the best one in this class.

Werner is an all-around talent and will go in the top half of the first round.

Dion Jordan, Oregon

Jordan is huge. At 6'7", he will enter the NFL as one of the biggest defensive ends.

He's also pretty good. He had 44 tackles, 10.5 tackles for loss, three forced fumbles and five sacks.

Jordan offers versatility by being able to drop into coverage. A 6'7" player who can cover running backs is quite the weapon for defensive coordinators to employ.

At only 243 pounds, Jordan needs to bulk up to be a consistent pass rusher in the NFL. However, he can play both defensive end in a 4-3 scheme and outside linebacker in a 3-4 scheme and should be a late first-round pick.
